Description

Technical Field

[0001] The invention relates to the technical field of laser scribing equipment, and specifically proposes a laser scribing equipment for manufacturing and processing perovskite photovoltaic modules. Background Art

[0002] Perovskite photovoltaic panels are a new type of photovoltaic technology based on perovskite materials as light absorption layers. The typical layer structure of perovskite photovoltaic panels usually includes the following parts: Substrate: It can be a transparent material such as glass or plastic, providing main support for other layers.

[0003] Electron transport layer: used to extract electrons from the perovskite layer.

[0004] Perovskite light-absorbing layer: the core layer, responsible for absorbing sunlight and generating electron-hole pairs.

[0005] Hole transport layer: used to transport holes to the electrode.

[0006] Back electrode: used to collect holes.

[0007] During the manufacturing process, these layers are often laser-scribed in order to form arrays of solar cells connected in series or in parallel. Laser scribing is a precise process that removes material in specific areas to achieve electrical isolation or connection without affecting surrounding materials. Depending on the design requirements, multiple layers of scribing are generally required, which usually involves the following steps: First scribe (P1): performed on the back electrode to define the area of ​​a single cell.

[0008] The second scribe (P2) passes through the hole transport layer to the perovskite layer, with the aim of electrically isolating adjacent battery cells.

[0009] The third scribing (P3): penetrates the electron transport layer and transparent conductive oxide layer until the substrate, ensuring electrical isolation between adjacent cells and preparing for the back electrode deposition of the next battery cell.

[0010] In the process of laser scribing photovoltaic panels, it is necessary to position the photovoltaic panels so as to perform precise laser scribing on the photovoltaic panels based on the positioning. Laser scribing is a non-contact processing method. In existing processing equipment or systems, an initial positioning mechanism is generally provided and a high-precision conveying system is equipped. Therefore, during processing, after the initial positioning of the photovoltaic panels is completed, it is generally only dependent on the precise start and stop conveying of the high-precision conveying system to achieve the conveying and positioning of the photovoltaic panels without corresponding repositioning. However, in actual processing, after the conveying system has been running for a long time, the mechanical parts will be affected by factors such as thermal expansion, the operating stability will be reduced, and the positioning accuracy will also be reduced. In addition, the photovoltaic panels will be affected by factors such as vibration of workshop production activities and airflow during transportation, and slight position deviations will also occur. In summary, in the existing photovoltaic panel laser scribing equipment system equipped with a high-precision conveying mechanism, it is necessary to set a corresponding repositioning structure.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] like Figure 1 and Figure 2As shown, a laser scribing device for manufacturing and processing perovskite photovoltaic modules includes a workpiece conveying platform 1 and a laser scribing mechanism 3.

It should be noted that the perovskite photovoltaic module described in the name of the present invention specifically refers to a perovskite photovoltaic panel, which is uniformly referred to as a photovoltaic panel hereinafter.

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the workpiece conveying platform 1 includes a conveying frame 11; the conveying frame 11 includes two horizontally symmetrically arranged supporting platforms 111, the supporting platforms 111 include side uprights 1111 welded on the fixed platform and supporting plates 1112 horizontally welded on the top of the side uprights 1111, the supporting plates 1112 are located on the plate surface of the connected side uprights 1111 facing away from the other supporting platform 111, and multiple pneumatic adsorption plates 1114 are horizontally welded on the opposite surfaces of the side uprights 1111 in the two supporting platforms 111, and the multiple pneumatic adsorption plates 1114 are evenly distributed in the plate length direction of the side uprights 1111, the pneumatic adsorption plates 1114 are existing vacuum adsorption platforms, and the upper plate surface of the pneumatic adsorption plates 1114 is evenly distributed with vacuum adsorption holes. In the present embodiment, the upper plate surface of the supporting plate 1112 is coplanar with the upper plate surface of the pneumatic adsorption plate 1114. During the processing, the two together constitute a supporting surface and are used to jointly support and place photovoltaic panels. It needs to be supplemented and explained that, in the present embodiment, the workpiece conveying platform 1 specifically refers to the conveying mechanism of the laser scribing processing area. In order to facilitate moving in and out of the laser scribing processing area, at least in the conveying direction of the workpiece conveying platform 1, a conveying mechanism for moving the photovoltaic panel into the laser scribing processing area and a conveying mechanism for moving the photovoltaic panel out of the laser scribing processing area should be installed.

[0041] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, a lifting frame 12 is installed on the conveying frame 11; the conveying frame 11 also includes a cross plate 112 horizontally welded between two side vertical plates 1111; the conveying frame 11 also includes a roller frame 121 located above the cross plate 112, and four guide rods 122 vertically slidably installed on the cross plate 112 are welded at the bottom end of the roller frame 121, and a No. 1 cylinder 123 is vertically fixed to the bottom end of the cross plate 112 by screws, and the output rod of the No. 1 cylinder 123 is fixedly connected to the roller frame 121 by bolts; a plurality of conveying rollers 13 are horizontally rotatably installed on the roller frame 121, and the plurality of conveying rollers 13 are evenly and alternately distributed in the plate length direction of the side vertical plates 1111 and the plurality of pneumatic adsorption plates 1114 in the supporting platform 111. The conveying roller 13 includes a roller shaft 131 which is horizontally rotatably mounted on the roller frame 121. The roller shaft 131 is a round tube structure with one end closed and the other end open. A plurality of roller bodies 132 are evenly distributed and fixed on the roller shaft 131 along the axial direction. A plurality of air holes 1321 which are connected to the roller shaft 131 are evenly distributed on the circumference of the roller body 132. The two ends of the roller shaft 131 pass through two side vertical plates 1111 respectively. In this embodiment, a pulley can be fixedly mounted at a position near the closed end of the roller shaft 131. The pulleys of the plurality of conveying rollers 13 can be synchronously driven by a synchronous belt, and the open end of the roller shaft 131 can be connected to an air pipe through an existing rotary pipe joint for introducing cooling air. When the output rod of the No. 1 cylinder 123 is fully extended, the roller frame 121 is at the highest position, and at this time the horizontal conveying section of the roller body 132 is coplanar with the upper plate surface of the pneumatic adsorption plate 1114. When the photovoltaic panel is placed on the supporting surfaces of the two supporting platforms 111, it also contacts with multiple conveying rollers 13 synchronously. Obviously, when the output rod of the No. 1 cylinder 123 contracts, the conveying rollers 13 descend synchronously with the roller frame 121, and the roller body 132 is not in contact with the photovoltaic panel and is in a separated state.

[0042] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, two positioning assemblies 2 are mounted on two supporting platforms 111 in a one-to-one manner; the positioning assembly 2 includes a side clamping mechanism 21 mounted on the supporting platform 111 and a side stop mechanism 22 mounted on the side clamping mechanism 21; the side clamping mechanism 21 includes two guide columns 211 horizontally fixed on the side vertical plate 1111, the central axis of the guide column 211 is vertically arranged relative to the conveying direction of the workpiece conveying platform 1, and a displacement frame 213 is installed on the two guide columns 211 for common sliding cooperation, a No. 2 cylinder 212 is horizontally fixed on the side vertical plate 1111 by bolts, and the output end of the No. 2 cylinder 212 is fixedly connected to the displacement frame 213; a plurality of uniformly distributed and arranged along the conveying direction of the workpiece conveying platform 1 are installed vertically and rotatably on the top of the displacement frame 213. The side clamping roller 214 and the supporting plate 1112 are provided with a plurality of avoidance notches 1113 for one-to-one avoiding the side clamping rollers 214; the displacement frame 213 is symmetrically welded with guide ear plates 2131 on both sides arranged along the conveying direction of the workpiece conveyor platform 1, and the guide ear plates 2131 are L-shaped; the side block mechanism 22 includes a No. 3 cylinder 221 vertically fixed to the bottom end of the displacement frame 213 by bolts, a bridge plate 222 horizontally fixed to the output end of the No. 3 cylinder 221, and two side block assemblies 223 assembled on the two guide ear plates 2131 in one-to-one correspondence, and the two side block assemblies 223 are horizontally symmetrically arranged in the conveying direction of the workpiece conveyor platform 1. Obviously, the plurality of side clamping rollers 214 are distributed between the two side block assemblies 223.

[0043] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the side block assembly 223 includes a lifting slider 2231 vertically slidably mounted on the guide ear plate 2131, a sliding base 2232 is welded to the top of the lifting slider 2231, a side block slider 2233 sliding along the conveying direction of the workpiece conveying platform 1 is slidably mounted on the sliding base 2232, and a return spring 2234 is welded between the side block slider 2233 and the sliding base 2232. The bridge plate 222 is horizontally welded between the bottoms of the two lifting sliders 2231. The support platform 111 is equipped with two adjustable contact assemblies 23 corresponding to the two side block assemblies 223, and the adjustable contact assembly 23 includes a roller seat 231, and a matching roller 234 is vertically rotatably mounted on the top of the roller seat 231 through a bearing; two guide pins 232 horizontally slidably mounted on the side vertical plate 1111 are welded to the roller seat 231; and an adjusting screw 233 threadedly connected to the side vertical plate 1111 is horizontally rotatably mounted on the roller seat 231. A wedge-shaped surface is provided on the side of the side block slider 2233, which is opposite to the other side block component 223 in the same positioning assembly 2; the mating roller 234 and the mating side block component 223 are distributed on the same side of the side vertical plate 1111, and when the side block component 223 moves toward the adjustable contact component 23, the mating roller 234 rolls in contact with the wedge-shaped surface of the side block slider 2233.

[0044] like Figure 1 and Figure 2 As shown, the laser scribing mechanism 3 includes a displacement frame 31 installed on a fixed platform and a laser head 32 assembled on the displacement end of the displacement frame 31. The laser head 32 is the execution end in the existing laser scribing equipment. The displacement frame 31 is used to drive the laser head 32 to move in the horizontal, longitudinal and vertical directions.

[0045] During actual processing, the photovoltaic panel will be automatically transported to the workpiece conveying platform 1 and will be in a suspended conveying state. At this time, the photovoltaic panel will be placed flat on the supporting surface composed of the supporting plates 1112 on the two supporting platforms 111 and the two rows of pneumatic adsorption plates 1114. Then the lifting frame 12 will drive the entire row of conveying rollers 13 to descend, so that the conveying rollers 13 and the photovoltaic panel are in a separated state.

[0046] Next, first start the No. 3 cylinder 221 to drive the side block assembly 223 to rise, so that the side block slider 2233 is at a height where its side block surface can form contact with the photovoltaic panel, and then start the two No. 2 cylinders 212 to drive the two displacement frames 213 to move closer to each other, so that the two rows of side clamping rollers 214 are synchronously close to each other, and at the same time, the wedge surface of the side block slider 2233 contacts the matching roller 234, and the matching roller 234 causes the two side block sliders 2233 in the same positioning assembly 2 to move closer to each other through the friction, and then when the two rows of side clamping rollers 214 contact the two sides of the photovoltaic panel, the two groups of side block sliders 2233 in the two positioning assemblies 2 synchronously contact the other two sides of the photovoltaic panel, so that the photovoltaic panel is processed and positioned. It should be noted here that the side clamping rollers 214 and the side block sliders 2233 only play a contact positioning role for the photovoltaic panel, and do not squeeze the side of the photovoltaic panel, that is, no squeezing and cracking will occur. Here, it should be added that, for photovoltaic panels of a certain size, their predetermined processing positions in the laser scribing processing area are determined. Before processing, the two positioning assemblies 2 can be adjusted to ensure their positioning accuracy. Specifically, the photovoltaic panel is accurately placed in the predetermined processing position. First, by rotating the adjusting screw 233, the matching roller 234 is moved to a position as far away from the corresponding side block assembly 223 as possible. Subsequently, the side clamping roller 214 is moved to make the photovoltaic panel contact with the two rows of side clamping rollers 214. Next, the adjusting screw 233 is rotated again to actively drive the side block slider 2233 to move through the matching roller 234, thereby making the side block slider 2233 contact with the side edge of the photovoltaic panel at the predetermined position, thereby completing the adjustment of the positioning assembly 2.

[0047] Subsequently, in the positioning state, in order to further stabilize the state of the photovoltaic panel, two rows of pneumatic adsorption plates 1114 are in a pneumatic adsorption and fixing state for the photovoltaic panel. In addition, cooling air is introduced into the conveying roller 13 while it is in a rotating state (in the separated state, no conveying driving force is generated for the photovoltaic panel), and the cooling air is discharged along the roller shaft 131 and the air hole 1321. The entire row of conveying rollers 13 is evenly distributed under the photovoltaic panel, and the cooling air is evenly distributed on the lower surface of the photovoltaic panel. During the scribing process, the photovoltaic panel can be cooled and dissipated as a whole in a timely manner to avoid the thermal stress deformation in the laser scribing process affecting the scribing quality.

[0048] Then, the laser head 32 is driven by the displacement frame 31 to perform laser scribing on the photovoltaic panel, and the first scribing, the second scribing and the third scribing are completed in sequence. After the scribing process is completed, the pneumatic adsorption plate 1114 and the two positioning assemblies 2 are released, and the side block slider 2233 is lowered to the initial height. Finally, the photovoltaic panel is transported out through the workpiece conveying platform 1.

[0049] The present invention provides a laser scribing device for manufacturing and processing perovskite photovoltaic modules, which is provided with two positioning assemblies 2 that cooperate with each other, and the positioning assembly 2 is provided with a side stop assembly 223 that can be raised and lowered to avoid position, so that the photovoltaic panel can be quickly repositioned during the processing and transportation of the photovoltaic panel; in the workpiece conveying table 1, a supporting table 111 that can be used to horizontally support and place the photovoltaic panel, and a whole row of conveying rollers 13 that can switch between states of lifting and lowering are provided, and the uniform distribution of multiple conveying rollers 13 and the cooling structure of the conveying rollers 13 themselves can uniformly cover and cool the entire panel surface of the photovoltaic panel to avoid thermal stress deformation in the laser scribing process, and in addition, the adsorption and fixing effect of the supporting table 111, on the basis of the processing and positioning of the photovoltaic panel by the positioning assembly 2, further improves the stability of the placement of the photovoltaic panel, avoids the problem of offset due to vibration, and also avoids the possibility of the conveying roller 13 causing offset to the photovoltaic panel when cooling by the cooling airflow.
